In the case of an access, the bits respond to a 0->1 change to trigger
the corresponding function.
If a request for changing the operating state is not successful, this
request is ignored. There is no error response.
Ambivalent bit combinations are treated in accordance with the follow-
ing priority list (highest priority bit 8, lowest priority bit 14 and bit 15):
•
Bit 8 (disable power stage) prior to bit 9 (enable power stage)
•
Bit 10 ("Quick Stop") prior to bit 11 ("Fault Reset")
•
Bit 13 (execute "Halt") prior to bit 14 (clear "Halt") and bit 15
(resume operating mode interrupted by "Halt")
